I am trying to request snapshot from Bloomberg through Python API using the example programs that Bloomberg provided with the package. Their own program doesn't work properly and I keep getting the error:
WARN blpapi_subscriptionmanager.cpp:1653 blpapi.session.subscriptionmanager.{1} Subscription management endpoints are required for snapshot request templates but none are available
blpapi.exception.UnsupportedOperationException: No subscription management endpoints for snapshot (0x00080013).
The part of the code that has the snapshot request is in main func:
def main():
"""main entry point"""
global options
options = parseCmdLine()
# Create a session and Fill SessionOptions
sessionOptions = blpapi.SessionOptions()
for idx, host in enumerate(options.hosts):
sessionOptions.setServerAddress(host, options.port, idx)
sessionOptions.setAuthenticationOptions(options.auth)
sessionOptions.setAutoRestartOnDisconnection(True)
print("Connecting to port %d on %s" % (
options.port, ", ".join(options.hosts)))
session = blpapi.Session(sessionOptions)
if not session.start():
print("Failed to start session.")
return
subscriptionIdentity = None
if options.auth:
subscriptionIdentity = session.createIdentity()
isAuthorized = False
authServiceName = "//blp/apiauth"
if session.openService(authServiceName):
authService = session.getService(authServiceName)
isAuthorized = authorize(authService, subscriptionIdentity,
session, blpapi.CorrelationId("auth"))
if not isAuthorized:
print("No authorization")
return
else:
print("Not using authorization")
# Snapshot Request Part:
fieldStr = "?fields=" + ",".join(options.fields)
snapshots = []
nextCorrelationId = 0
for i, topic in enumerate(options.topics):
subscriptionString = options.service + topic + fieldStr
snapshots.append(session.createSnapshotRequestTemplate(
subscriptionString,
subscriptionIdentity,
blpapi.CorrelationId(i)))
nextCorrelationId += 1
requestTemplateAvailable = blpapi.Name('RequestTemplateAvailable')
eventCount = 0
try:
while True:
# Specify timeout to give a chance for Ctrl-C
event = session.nextEvent(1000)
for msg in event:
if event.eventType() == blpapi.Event.ADMIN and \
msg.messageType() == requestTemplateAvailable:
for requestTemplate in snapshots:
session.sendRequestTemplate(
requestTemplate,
blpapi.CorrelationId(nextCorrelationId))
nextCorrelationId += 1
elif event.eventType() == blpapi.Event.RESPONSE or \
event.eventType() == blpapi.Event.PARTIAL_RESPONSE:
cid = msg.correlationIds()[0].value()
print("%s - %s" % (cid, msg))
else:
print(msg)
if event.eventType() == blpapi.Event.RESPONSE:
eventCount += 1
if eventCount >= options.maxEvents:
print("%d events processed, terminating." % eventCount)
break
elif event.eventType() == blpapi.Event.TIMEOUT:
for requestTemplate in snapshots:
session.sendRequestTemplate(
requestTemplate,
blpapi.CorrelationId(nextCorrelationId))
nextCorrelationId += 1
I don't know if endpoint and subscription management endpoint are 2 different things because I have one other code working properly and the endpoint is the IP of the server I am pulling the data.
